Problem 2: Incorrect Input Source Selected
Solution:
- On the projector's remote or control panel, select the correct input source that matches the video cable connected to your laptop (HDMI, VGA, DisplayPort, etc.).
- Use the projector's menu or source button to cycle through the available input sources until the laptop's display appears.
Problem 3: Display Settings on Laptop
Solution:
- On your laptop, access the display settings. Depending on your operating system, navigate to the control panel or system preferences.
